Chinese researchers create smallest amphibious shape-shifting robot

Chinese researchers at Tsinghua University have developed the world’s smallest and lightest wireless amphibious robot, capable of shape-shifting to adapt to different environments, Anadolu Agency reported. Measuring just 9 centimeters (3.5 inches) in length and weighing 25 grams (0.88 ounces), the robot can move at speeds up to 1.6 meters (5.2 feet) per second on land.

The team designed a miniature actuator that enables the microrobot to continuously change shape and lock into specific configurations, enhancing its flexibility and functionality. This actuator is integrated into a modular building block design, allowing the robot to transform its structure for running and flying, showcasing remarkable agility and maneuverability.

The robot consists of multiple components, including rotors, a motor, a controller, and a power supply, all powered by the innovative actuators. Led by Professor Zhang Yihui, the research marks a significant advancement in microrobotics, with potential applications in various fields requiring versatile, compact robotic systems capable of operating both on land and in water.
